Concept:The balance of trade is the monetary difference between a country's total exports and total imports.
Explanation:Balance of trade is usually expressed as total exports minus total imports.
A positive result occurs when exports are greater than imports, creating a trade surplus.
A negative result occurs when imports are greater than exports, creating a trade deficit.
In this case, the balance of trade is
−$20 million, which is a negative figure.
This negative figure means that imports exceed exports by
$20 million.
Therefore, the country's import volume is greater than its export volume.
Answer:Option A: import volume is greater than export.
